axles. It is evident that the particular location o' these springs b between the axleboxes and frame B is immaterial. By the construction shown .I am enabled to have the Inidvdle part of the truck free or unobstructed ,5 nd for the disposal of the electrical connections or apparatus.

B4 is the pivot-plate for connection with the car-body.

A truck may be pivoted at each end of the car-body, if desired, in which case it would be like any ordinary car having eight wheels. Ag'iin, I may consider the frame B as the ve lele-frame and as a complete vehicle, as it would be if the usual box or body were built upon it like an ordinary street-car.

EE areythe electric motors and have the well-known horseshoe field-magnets. To each side Aof these ma nets and their polepieces are secured braclets or frames F, having journals or bearingsf, which t upon the ax es and by which the motors are supported upon the said axles. These bearings or journals arefon each side of the motor and considerably separated. The axles may pass between the field magnets. struction the motor-shafts g are caused to re main at a fixed distance from the axles irrespective of the movement of the motor about said axles, and the yokes or keepers of the magnets of the motors are situated parallel with and in close proximity to the drivingaxles. To tle ends of the motor or drive# shafts are secured the pinions G, which preferably have considerable width. Meshing with these pinions and secured to the axles are spur-wheels H.

To revent the free revolution of the motors a out the axles andtake up the jar, I connect them by links J withthe free end of a two-armed spring J, which is carried by a cross-frame t', secured to the equalizing frames or bars B3. For simplicit and to cause the strains on the two en s of the spring J to be in the same direct-ion at the same time the Ymotors are arranged to face eachother. This enables the adoption of a cheap and effective construction. It is to be understood, however, that' I do not limit myself to any particular elastic or flexible sup- 5o porting connection for the motor, as my in- \ention.comprehends the elastic connection broad A-coil or other form of spring may be used in lGlace of.' the flat 'plate-spring.

ency to revolution'of the armatures will be to oscillate the motors and put the springs J under tension. As the resistance of the springs is' adually increased the tendency to rotate t e axle also gradually increases, and by this connection the effective power of the motor on starting is greatly increased. The spring J acts the same whenV the motor is run forward or backward.

It 4will be observed that the connection of By this conow as the motors start up the first tendthe motors with the spring-supports at the Ifree ends is such that the connection is interposed between two portions of the spring devices, one opposing anupward motion of the free end of the motor and the other opposing a downward motion thereof. In the case where the coiled springs are used, Fig.- 3, the transverse lframe 'i carries at its top lateral extensions K, from which bolts I2 depend and pass throlrlgh an extending lu or projection from the motor. above and below this projection from the motor and surrounding and carried by the bolt, so as to permit, in effect, an upwardl and downwardly acting sprin -buffer to ta e up the jar or vibration of t e free end of the motor. y

The cross-bars I and equalizing-bars B3 constitute a frame carried upon the axles, and said, frame acts as the support for the springs connecting with the electric motors and is practically at a lower level than the motors and extends transversely across the The springs are arranged l vehicle below the springs which support the l,

motors. Y

While this invention is specially designed for railway-cars, it is evident that it equally applies to vehicles of all descriptions, whether it is adapted to run up on rails or roads. Hence in`using the terms car and carbody I do not intend to confine myself to any s ecial type of vehicle.

So Far as my invention in this application is concerned, it is immaterial what source of electrical power may be employed.

I do not limit myself to any particular details of construction, as they may be modified in various ways without in the least departing from the principles of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a motor-truck, the combination with4 the axle-box frame having side bars, of a motor sleeved on one of the truck-axles, a crossbar extending between the side bars of said frame, and a connection for the free e'nd of the motor comprising a plurality of oppositely-aoting springs supported by said crossbar.

' 2. In a motor-truck, the combination with the axles, of an independent frame hung from the axles, a motor sleeved to one of the axles, a cross-barincluded in said frame, and oppositely-acting springs above and ,below a connection with the free end of the motor, said sprin s4 connecting with said cross-bar.

3. In a motor-truck, the combination with the axle-box frame having side bars, of a motor sleeved on one ofthe truck-axles, a crossbar extending between the side bars of said IOO frame, and a connection for the free end of the motor comprising a plurality of oppositely-acting springs supported by said cross- 5 bar, an electric motor hin ed to the axle and having its free end directe toward the transier, and e double spring-support for the free end of the Vmotor connecting with said transverse bar one portion of said spring 1o receiving the upward and the other portion the downward til rust of the motor.

5. in en electicaiiy-propeiied vehiele, the combination of the Wheels and two exies, sl truck-frame carried by the axies independent r 5 of the vehicle-body and havin a transverse portion intermediate of the a es, en eieotrio motor hin ed to each of the axles end having its free en directed toward the other axle so as to brin the free ends of the two motors zo between t e axles, and a se arate don'oie spring connection between t e transverse portion of the truck-frame and each of the eiectric motorsat their free ends whereby both the upward andv downward thrusts of e5 the motors are received upon separate porw tions of the same spring devices.

t 6. In a motor-truck, the combination with the axie-box-fra1ne having side bars, of a Inotor sleeved on one of the truck-exten, a cross- 3o bar extending between the side hars of said iframe, and a spring-sugport for the free end of the motor carried y the cross-bar and .having a-springaction upon the motor both in the upward and downward movements of its free end.

7. In s. motor-truck, the combination with the aides, of an inde endent frame hung from the axles, a. motor s eeved to one of the sides, end a spring-support for the free end of the motor carried by the independent frame and comprising twolportions one exerting aspring action against t e rising of the free end oi the motor and the other exerting a spring action against the downward movement of the free end ofthe motor. i

8. In a motor-truck2 the combination with the unies, of an inde endent frame hung from the axles, a motor s1P a spring-sup ort for the free end of the motor carried by t e independent frame and comprising two portions one exerting asprin action against the rising of the free end o the motor onlv when the motor is in operation and the other exerting a spring action against the downward movement of the free'end of the motor both when the motor is in and out of operation, and means extending from the free end of the motor for forming a connection with the springt-support intermediate o its two portions.

In testimony of which invention I hereunto set my hand.
